MINIATURE SAFETY RAZOR Filed May ll, 1957 Patented Dec. 13, 1938 UNITEDSTATES PATENT OFFICE.

1 Claim.

My invention relates generally to safety razors, and more particularlyto a miniature safety razor particularly intended for use in cuttinghairs from the nostrils and ears.

The principal object of my invention is to provide a relatively simple,practical and inexpensive miniature safety razor that is very compact,and which includes a holder, a blade, and a guard, which, when properlyassembled, provides simple and effective means for conveniently cuttinghairs from the nostrils and ears, and the construction of the razorbeing such that the guard that overlies the blade, while the latter ispositioned on the holder, is provided at its rear erid ll with aresilient clip that engages the rear portion of the holder in order tofirmly retain the blade in proper position upon said holder.

A further object of my invention is to provide a miniature razor of thecharacter referred to,

wherein the holder, blade and guard are provided with curved forwardedges in order to enable the razor to be more conveniently used in thenostrils and ears.

With the foregoing and other objects in view,

my invention consists in certain novel features of construction andarrangement of parts that will be hereinafter more fully described andclaimed and illustrated in the accompanying drawing, in which:

Fig. 1 is a top plan view of a miniature razor constructed in accordancewith my invention.

Fig. 2 is a vertical section taken on the line 2--2 of Fig. 1.

Fig. 3 is a top plan view of the holder.

Fig. 4 is a top plan view of the blade.

Referring by numerals to the accompanying drawing which illustrates apreferred embodiment of my invention, Il) designates a plate, preferablyformed of metal, which serves as the 4o frame or support for the blade,and the front edge of this plate is practically semi-circular in shapeand provided with a series of teeth II that function as guards for theedge of the razor blade while the same is in use.

Formed integral with the underside of plate Ill, and disposed at anangle of approximately 30 or 40 relative thereto, is a stud I2 in whichis formed a threaded recess for the accommodation of the threaded stemI3 0f a handle I4. This handle may be of any desired size and shape-Formed on top of the plate I0 adjacent its side edges, are upwardlyprojecting studs I5, and projecting upwardly from the center of saidplate is a stud I6.

The razor blade I 'I, which is illustrated in (cl. sof-3s) Fig. 4, isformed from thin hard metal, and its forward edge I8, which issubstantially lsemicircular in shape, is sharpened.

Formed in the sides of blade I1 are notches I9 which, when the blade ispositioned on the holder, 5 receives the stud I5. Formed through thecenter of the blade is an aperture 20, which, when the blade is appliedto the holder, receives the stud I6.

Thus the engagement of the studs I5 in the 10 notches I9 and the stud I6in the aperture 20, firmly holds the blade against any lateral ortwisting movement while positioned upon the holder.

When the blade is positioned on the holder, the l5 sharp forward edge I8of said blade occupies a position parallel with and slightly inset fromthe forward ends of the guard teeth II on the front edge of the holder.

A combined guard and blade holder comprises 20 a plate 2| of thinresilient sheet metal, the front edge 22 of which is semi-circular inshape so as to conform with the shapes of the forward ends of the bladeand holder, and when this retaining member is positioned on the holder,the plate 25 2| overlies the blade I1, and with the curved front edge'22 positioned a slight distance inwardly from the sharp edge I8 of saidblade.

This arrangement provides a guard to prevent the sharp edge of the bladefrom cutting the 30 skin while the razor is in use.

The rear end of the guard plate 2| is bent downwardly and inwardly toform a resilient hook 23, and adjacent the end of said hook the metaltherein is indented or pressed upwardly to 35 form a rib 24 which, whenthe guard plate is applied to the razor, occupies a transverselydisposed groove 25 that is formed in the under face of the holder I0adjacent its rear edge.

In assembling the parts of the razor for use, 40 the blade I1 ispositioned on plate Ill with the projections I6 seated in the aperture20 and the studs I5 occupying the notches I9.

Thus the blade is held against movement in all directions upon the plateI0 and to secure the 45 blade in such position the forward portion ofthe plate 2I is positioned on top of the rear portion of the blade, andsaid plate is moved forward until the hook 23 engages the rear portionof plate I0 with the rib or indentation 24 seated in 50 the groove 25.

Thus the parts of the razor are firmly retained in assembled relationand said razor may be con veniently used for cutting hairs from thenostrils and from the ears. 55

In order to be effectively used, the parts Il, I1 and 2| mustnecessarily be small in size, for instance the over-all dimensions ofsaid parts when assembled for use should' not be greater thanthree-eighths of an inch.

The forward edges of the plates I0 and 2| and blade I1 are curved inorder to conform to the curvature of the surfaces of the nostrils andthe tapered openings in the ears, and such arrangement adds materiallyto the effectiveness of the razor while in use.

Thus it will be seen that I have provided a miniature safety razor thatis relatively simple in construction, inexpensive of manufacture. andvery effective in performing the functions for which it is intended.

' It will be understood that minor changes in the size, form andconstruction of the various parts of my improved miniature safety razormay be made and substituted for those herein shown and described withoutdeparting from the spirit of the invention, the scope of which is setforth in the appended claim.

' I claim as my invention:

A miniature safety razor comprising a handle. a plate detachably appliedto. said handle and occupying a position immediately adjacent the endthereof, said plate being inclined with respect to the axis of thehandle, the front lower edge of which plate is semi-circular in form andprovided with substantially parallel teeth, a lug projecting upwardlyfrom the center of the top of said plate, lugs formed on top of theplate adjacent the sides thereof, a blade removably positioned on top ofsaid inclined plate, the sharpened edge of which blade is semi-circularin shape and overles the teeth on said plate, said blade being providedwith an aperture and notches for the reception of the lugs on the uppersurface of said plate, a guard plate overlying the blade, the front edgeof which guard plate is semi-circular in form and occupies a positionadjacent the sharp edge o! the blade, a depending hook projectinginwardly from the rear edge of said guard plate and there being atransversely disposed groove formed in the under side of said inclinedplate for the reception of the free end of said hook.

VALENTINE HEINRICH.
